RE: st: xtmelogit calculation time

Starting values can be passed in as an option. Honestly the easiest thing to do is go to the menu system and look in the last tab. Down near the bottom of it will be starting values. Run a model with some values in there and you should see the syntax easily enough.

Hi Jeph,
really interested in your response as am having similar
issues to Changwoo. How do you go about using these earlier starting
models as starting values for the later more complex models.
